BOX.

Specification of Letters Patent.

Patented July 19, 1921..

Application filed January 23, 1920. Serial No. 353,524.

To all whom it may concern.

Be it known that I, LOUIS BINDER, a citizen of the United States, and aresident of Newark, county of Essex, and State of New Jersey, haveinvented certain new and useful Improvements in Boxes, of which thefollowing is a specification.

This invention relates to an improved lOOX in which the lid is heldagainst accidental opening by the friction of an inner sheet on the lid,this sheet being so attached to the lid that it has a bellows-likeaction, that is, the pressure of this sheet on the goods inside the boxis equalized and it forms a flat surface for engaging goods in the box.

A box of this kind is particularly adapted for use as a cigarette boxand for similar purposes, no ridges or other inequalities on the insideof the cover affecting the contents, as the pressure is the same allover and the lid is held shut without the more expensive constructionwhich utilizes a flanged lid fitting over the outside of the box andhaving its edge in contact with a thickened lower portion forming aledge.

Another object of this invention is to provide a box in which theclosure is tight, even through the lid is not forcibly moved to itslimit of inward movement, the bellowslike inner sheet being preferablymade so that it engages the inner faces of all the walls of the box.

The invention is illustrated in the accompanying drawing, in whichFigure 1 is a perspective view of a box, the lid be ng shown open, thislid being made according to my invention. Fig. 2 is a cross-section ofthe box shown in Fig. 1, but with the lid shut. Fig. 3 is a blank fromwhich the inner sheet on the inside of the box can be made, and Fig. 4is a perspective view of one corner of the inner sheet folded over,ready to be applied to the inside of the lid.

In the form illustrated I show a box 10, which is of the usualrectangular shape, having the side walls 11, the front wall 12 and theback wall 13, a lid 14, usually fiat and made of cardboard, as is thebox, being hinged, usually by means of a strip 15 which is pasted to thelid and to the box and thus permits a swinging of the lid and also aslight movement of the lid relative to the hinge, but permits the lid toseat itself in the proper position.

On the inside of the lid I arrange a sheet 16, this sheet being flat andbeing secured to the lid so that all parts of the sheet have a movementrelative to the lid, that is, toward the lid, so that pressure on thesheet is equal when the lid is forced down to press the sheet againstthe contents of the box. This is a decided advantage where soft oreasily breakable articles, such as cigarettes, are packed in the box.

The sheet 16 is usually proportioned so that all its edges fit againstthe inner faces of the vertical walls of the main or body portion of thebox. The movement of the sheet relative to the box is usually broughtabout by constructing the parts so that there is a bellows-like actionof the sheet toward the lid.

In the form shown the sheet is provided. with a fold 17 around itsoutside edge, this fold 17 being folded inwardly and terminating in afold 18 which is bent outwardly so that a reverse fold is provided, theupper face of the outwardly extending fold 18 being secured to the innerface of the lid, usually by means of glue, although it will beunderstood that other means of fastening the sheet can be employed. Whenthe lid is moved to closed position, the flexible hinge permits thesheet 16 to fit inside the box, but the folding of the sheet 16, thatis, its edges, permitting a somewhat rounded surface that assists theseating of the sheet, and the edges form a tight joint with the innerfaces of the walls, so that any contents of the box that might losestrength or flavor by reason of any opening in the box, retains suchflavor.

The en'd19 of the lid is usually made so i that it extends slightlybeyond the box so that the lid can be raised more easily, and it will benoted furthermore that when the lid is shut, the forward end of thesheet, resting against the inner face of the front wall 12, is below thelevel ofthe point where the lid swings. Due to its construction, bothwhen the lid is opened and when it is shut, it snaps, that is, the frontedge of the sheet is pressed toward the lid 14: when the lid is beingswung, and snaps into position as the closing is completed, and when thelid is raised the front edge of the sheet drags on the inner face of thefront wall 12, requiring a little pressure to force the lid open, the

sheet 16 snapping into its ordinary position when the front edge of thesheetclears the top edge of the wall 12.

There is thus provided a box with a neat exterior appearance andsmoothtop andbOttom surfaces by means of which the goods are heldwithout possibility of bending or breaking, and the lid is held againstaccidental openingysince a positive pressure is necessary to get the lidopen.

It will be understood that various modifications can be made in theform. and arrangement of the parts without departing from thescope ofmyinvention.

I-claim:

' 1. A box comprising a body portion with sidewalls, a lid, and a flatsheet on the inner side of the lid and secured. thereto and forming apart thereof so that all .parts' of'the flatvportion of the sheet aremovable toward the lid and V contents of the box.

- 2. A box comprising "a body portion with side walls, alid, a fiatsheet on the inner side of the lid and forming a part thereof side thewalls, sheet-so that itis normally closely adjacent "to the lid and hasabellows-like action tocan thereforepress evenly on the January, 1920.

box, the edges of which.-she'et {are adapted to engage the inside facesof the side walls, and means for attaching the sheet so that it has abellows like action toward the lid.

3. A box comprising a body portion with side walls, a lid, a flat sheeton the inner side ofthe lid and approximately fitting in and means forattaching the ward the lid.

.4. A boxeomprising a bodyportion, a lid, and a sheet to fitrinthe boxand having an inwardly turned foldon each edge, each of said foldsterminating in an outwardly .turned fold, said ,lastmentioned foldsbeing secured to the inner faceofthe lid so that a-bellowseli'ke actionofthc sheet toward the lid ;is possible.
